In the same way baskets 51, 52, 53 and 54 were carried' within the chamber of said trunk to their illustrated locations. Basket 55 has passed through the chamber and is shown in the unloading posi- Basket 56 is shown on ramp a8 beneath'the lower part of belts 48. Basket 57 is shown in place on elevator platform 74. Driver sprocket wheels 58, 58' are each fastened to a short shaft 59 each of which is mounted for rotation in a bearing fastened to the side wall of one of recesses 10 near the rear end of the trunk. On the outer end of each of shafts 59 is fastened bevel gear 60 engaged with bevel gear a60 fastened on the lower end of one of diagonal shafts 61'which is mounted for revolution in bearings fastened tosaid trunk. On the upper end of each of shafts 61 is fastened bevel gear'62 engaged with one of bevel gears which'are fastened on the ends of shaft .64. Shaft 64 is mounted for revolution in bSlIlIlgS fastened on top of said trunk disposed across the same. Spur gear 63 is fastened'on said shaft 64 engaged with spur pinion 68 fastened on one end of short shaft 67 which is mounted for revolution in a bearing bracket fastened on the top of the trunk. Also on shaft'67 is fastened worm wheel 66 engaged with worm 69 fastened on the other end of the shaft of said electric motor 43.

orm'wheel 66 is relatively of large diameter with a large number of teeth, spur pinion 68 has'relatively few teeth, spur gear 63 has relatively a large number of teeth and bevel gears 65, 62, 36 and 33 are preferably of the samediaineter so that shaft 59 and sprockets 58 thereon revolve very slowly rela-. tively to motor 43. Idler sprockets 70, one of which is shown in Fig. 3, arefastened on short shafts e70, 6670, see Figs. 1 and 3, and mounted for revolution in bearingsfastened .to the sidewalls of recesses 10, 10, one of which isshown at Z170 in Fig. 1, inchain relation with sprockets 58, 58, and on each pair of sprockets 58, 70 is placed one of holdback chains 71 engaged therewith. The folds of chains 71, 71 are disposed longitudinally in recesses 10, 10, and the upper part of each of said chains is supported by bar 72 fastenedto the side wall of each of recesses 10. At spaced distances onchains 71 are fastened lfiold-back lugs 73 projecting outward there-- rom.

Elevatorplatform 74 is between pairsof guide posts 22, 22 and 23, 23 in front of the front end of the drier, and when in its full-line position is at the forward end of ramp tracks (L8, 058 and flush with the upper surface of the horizontally extended flanges thereof. 5 In the front and rear side' edges of platform 74 are pins 7 5, 75 to the rear of and'adja cent guide its posts 22, 22 to prevent forward movements of said; platform. Forward of saldfpo'sts and proximate thereto in sa d platformedges are the lower ends of links 77, 77 engaged on pins 76-, 76 in said platform edges and theselink ends stop said platform fromconsiderable rearward movements. The upper ends of said links 77, 77 are mountedon the ends ofrod-78L Pins? 9, 79'are set in said edgesof platform 74 imforward of the center thereof and with each of them is engaged the lower end of one of li-nks 80 the upper end of which joins the upper end of said link 77 in engagen eiit with one end of rod 78; Pin 7 9 is engaged in slot 81 and while the platform issupported bylinks 77, 80 and 77, 80 the front end of the platform may be raised to oscillate on pins 76, 76, ,On the rear edge of platform 7 are twohooks 82 opening upward; lvvhen the platform moves upward to the level of the upper fold of belts 48 these hookswill engage'with pins 85, in lugson bearings 47 and stopfurther upward movement of the rear edge 'of the platform while the front edge thereof may move farther upward under the pull of llnks 77' on pins V Tot-he center of rod 78 is fastened the lower end of rope 83 which is rove' oversheave 84 'inounted for revolution on a pin in a bearing on frame beam 24; A basket rolling down ramp a8 will roll upon elevator platforinT where its farther progress is'arrested by stop block a'fa thereon may-be rai'sedby; pulling downward on the free end ofropes 83till said platform has been raised to his tilted position atfll with hooks 82 engaged with pins 85 and saidibasket will then roll off onto belts 48 if the'front end of said belts is unoccupied; It

is assumed that basket 49 shown in full lines in place on the front of belts 4-8 had-previously passed through the positions indicated by basket 57 in full lines and then in its dotted- "position at 57 whence it may roll onto said belts.

Short shaft 86 is mounted for oscillation in bearing fastened to the upper front side wall of the trunk and to the-external end 'of said shaft is fastened hammer handle89 to the upper end of which is" fastened bell hammer 90. The other end of shaft-86 extends Within he drying chamber and to 1t 18 fastened arm 870a the freee'nd of which-is mounted small wheel 88 fem-evolution. VVhenwheelSS falls downward to its dotted position at 88' ham- 1118190 moves to 90 and strikes bell 91. I

Sho rt shaft 92 is mounted for oscillationin a bearing fastened to the upperp'art of the frontwall "ofthe trunk near its front-end and has crank 95 fastened thereto on its outerend'. To the other end ofsaid'crank is pivoted connecting rod 96 the upper end of which ispivoted to crank 97 fastened to one end of short shaft 98 on which is fastened front door dog To the inner endof shaft 92 within the drier is fastened'arm 93 and on the outer end 1 in said rails forward ,of aid stops.

basket comes to" rest at'an elcvationabove rampsaS, aS beneath and'the'b'asket is, free to be revolved on j said gudgeonsin the of this arm is mounted smallwheel 9atfor revol'ut ion. I Whee194 is shown in fulllines in its lower position which causes dog 30 to occupy its full-line position where it is engageable by door catch 27. But as wheel'94 is moved upwardto' its'dotted position at 94 dog 30 is forced backward to its dotted position at 30 out-of engagement with said door catch;

Centrifugal exhauster 99is installed on top from the front end thereof. 1

' Element-housing 101 is open at its rear end and connects with along'opening 102 across the top wall of the-trunk adjacent front door 'casingrll, ,Within housing '101 are-mounted electrical heating elements some of-which are indicated at 103. 'lVhen the three trunk doors are closed and exhauster 99 is operating; air is drawn through heating elements 103 and through the entire length of the trunkand dis- 1 at charged from the exhauster outlet which in practice is connected with a pipe leading without the building. Then if the elements are hot the air in passing thereamong will become heated and have the ability to take up-the1 moisture from such damp articles as maybe in said trunk through which it must pass. An

electric air heater is shown becauseits disclosure is simple.- In practice I prefer'to use steam'colls 111, place thereof. V, a As stated, when the baskets pass through rear door 13 they roll over trap door18 de pressing the same to its dotted position at 18 and before each of saidfbaskets leaves the trapdoor its gudgeons bear upon ramp rails 104:, 104, which are fastened to the upper ends of frame uprights b8,-and the basket passes downward rollingon said rails till platform rails 105,105 are: reached at the bottom of said cram-p. On the rearend of;

rails 105 are stops 107" which arrest ,the

farther rearward niovem'ent ofsthe;basketgudgeons'which enter grooves or; notches 108 lere the notches." Passage-ways 106for the basket gudgeons are provided between thefadjacent ends of rails-104 and 105 and,when desired; *abasket resting on rails105 may be pushed j forwardout of notches 108 and the gudgeons thereonwill have no supports'after passing I through openings 106 whenlth'e basket willdrop to bearl on ramps a8 and be free to roll forward down the 821116.

The laundryxbaskets'usedin my drier are all alike and one of them dd, is shownfon a larger scale ineEigsr5 and 6. In shape the baskets are hollow cylinderswith closed endsll'fiil v ms 109, 109centrally onto each of which is fastened a gudgeon a49. Bands 110, 110 are fastened to each end and extend toward each other forming parts of the body adapted to bear on canvas belts 48, 48. The intervening part of the'basket is preferably made of wire screen and has an opening for the admission and removal of wash. This opening is closable by hinged door 113 which may be fastened by latch 114. A. transverse central partition 111 divides the basket in equal parts, and longitudinal ribs or baiiies 112 are fastened to the interior of the basket body.

In operation: Assume that all parts are in their. illustrated full-line positions, that motors 43 and a99 are running and that heating elements 103 are supplied with electricity, then hold-back chain belts 71, 71 are moving very slowly in the direction indicated by the arrow in Fig. 3 and canvas belts 48 are moving much more rapidly in the same direction. Basket 49 occupied by wash just removed from the centrifugal driers is being moved toward closed door 12 by belts 48 and an operative pulls down on the free end of rope 28 till door 12 is fully open and catch 27 thereof is engaged with dog 30 which retains said door in its open position. Basket 49 passes within the trunk on said belts. lVhile door 12 was being opened door 13 was also opened allowing basket 54 to roll on trap door 18 depressing the same, against the reaction of spring 20, to its dotted position, against wash from basket 55 and sent it forward on ramp a8'p'roviding room on bars 105 for approaching basket'54; When basket 54 passes beyond'the end of trap door 18 it is returned toits full-line position by spring 20 thus closing the floor. opening in the trunk and completing the closure of the chamber. 7

When basket 49' entered the chamber the front end of the belts 48 became free for another basket iand the operative at the-front end of the drier raises platform 74 by pulling V downward on the free end of rope 83 and said basket 57 is carried to' its dotted position at -57 in a way already explained. From this position it easily rolls to the place on belts 48 previously occupied by basket 49 and moves is off of the elevator platform the latter is allowed to return to its lower position.

In Fig. 3 empty basket 56 is shown on folds disposed to bear on the top of the baskets as they roll downward on ramp a8. The presence of these belts on the baskets prevent the latter from'moving down the ramp at an accelerated rate and compel them to roll down under the control of said belts. In this manner basket 56'has passed over the ramp and onto platform 74 where it occupies the place vacated by basket 57 as described. While on the elevator platform baskets and amid the contents thereof, carrying away moisture therefrom, and escapes through the exhauster outlet.

Basket 49 is carried on belts 48 at their rate of movement through open door 12 till its gudgeons a49 contact with the rear side of one of chain lugs 73, which moves very slowly through the trunk, then said gudgeons move through the trunk at the same slow rate as the chain while the hasket periphery on the belts 48 continues to move with said'belts resulting in the rotation of the basket on said gudgeons with a peripheral rate equal to the rate of said belt movement as the entire basket slowly advances through the heating chamber at the rate of said chain. This relatively more rapid rotation in the hot chamber of the baskets moving slowly through the same causes the contents of the baskets to cascade from the basket baffles as they move upward in rotation and allows the hot air moving through the chamber to have access to the folds of said contents and promotes the rapid drying thereof. Expressed in another way: Chains 71 do not convey the baskets through the drying chamber, neither do lugs 73 thereon engage with gudgeons (149 on the baskets but rather they serve as stops for the gudgeons. Belts 48 convey the baskets through the chamber by contact with the peripheries thereof. The baskets are free to roll off or on the belts when not otherwise prevented. Because chains 71 move slower than belts 48 gudgeons 049 are caused to bear against the rear edges of the chainlugs 73 and thus the baskets are caused'by the belts to revolve in a backward toward closed door 12. As soon as .basket 57 direction while the said belts carry them forward through the chamberat the same rate i-ng chamber shown has a capacity for five baskets which are caused to enter and leave the "drying chamber consecutively one at a 3 J as said chains travel therethrough; The drytime and all are subjected to the dryingv means simultaneously. ,This arrangement promotes Y quantity drying'with few' operatives who are continuously employed in attending on the dryingoperations.

As stated, one ofthe baskets inits course through the trunlrhaving reachedthe location therein indicatedlby, has raised wheel 88 and caused bell hammer 90 to be removed from: close proximity to hell 91, :Then, as said basket moves-Lon, wheel 88 is allowed toldrop' causing said hammer to fall and strike the ball which serves, as Warning to the opera} tive in front'of the drier thatthere is room the front end thereof for another basket, and

he raises. the door to allowthat basket whiclr of the trunk and partly or fully providing air for the exhauster thus reduci-ngthe presf sure at the entrance of the heater housing and allowing the air within the heating chamber to come. to rest. This isaa desirable condition just prior to the. opening of. the front vdoor because then little cold air willent-er the hot chamber While the front door is open for a e1 Zr 5e ef a d hamb r, a g idgei i as:

Ap- P fly 1 he ont ary; h llus rat d con struction provides for the opening of the front door to. begin before the commencement of the opening; of door l3-in that the point-of fastening of rope 31 to rgpezs is belowsheaye 25. which permitssome upwardmovement of closed door 12 before rope 31 begins, to pull on door 13.] But, of course, bythe simple change of construction of shortening arm l5, and fastening rope 31 to ropev28 at a point on top of-sheave 25. when bothv doors are closed, the opening'of 'slaidl'door's by a downward pull olirope besimultaneous.

It may easily be understood that eif the rear end of the, trunk is desired to be the hot testit may be attainedby placing the exhauster on the lfronten'd of the trunk and the heating elements on the-rear end thereof,
